This is a fascinating topic. I've never been attracted to fasting, mostly because I assumed that it would have a negative effect on metabolism, putting you into some kind of starvation mode. This discussion makes me want to research it more.

I don't really view it as a weight-loss strategy for me, but the side benefits sound interesting. I also think it sounds liberating and likely to produce a different mindset.

Can anyone with experience talk a bit more about exercising while fasting? I would be concerned about muscle loss, and wouldn't want to disrupt my routine too much, or make it harder to get back to "normal."

Also, can anyone comment if there are any effects that would interfere with daily activities, especially work?
